SPECIFICATION forming part oLLetters Patent No. 358,429, dated March 1, 1887.

Application filed March 14, 1885. Serial No. 158,887. (No model.)

To all whom it may concern:

Be it known that I, GEORGE LGHAPIN, a

citizen of the United States, and a resident of -tion complete for use; Fig. 2, a vertical sectional elevation of the top portion of the same; Fig. 3, a modification of Figs. 1 and 2.

This invention relates to an improvement in that class of fire-extinguishers which are to be held by the hand andthe extinguishingfluid ejected onto a fire, and they are to be used more especially for extinguishing incipient fires and fires in inclosures and build ings; and the nature thereof, in brief, is as follows: A hollow frangible nipple with an externally-closed head, and of the required size for the rapid escape of fluid, but considerable smaller than the tube,isinserted in a surrounding body which will support the nipple and form a tight connection with the metal tube, the headed portion of the nipple projecting far enough beyond the tube and surrounding stopper readily to be broken off for the liberation of the fluid contained in the tube.

A serious difficulty has been encountered in those tubular fire-extinguishers which are held by the hand to throw the fluid on a fire, in that, when closed by corks or by metal heads tightly enough to hold the fire-extinguishing fluid, the people in whose hands they are placed cannot open the tubes for use. By means of my invention these difficulties have been overcome, and by carrying it into practice the construction is as follows:

A represents a sheet-metal tube, which is preferably made of tin-plate, and as a conthe tube A, but is considerably smaller than the tube, that it may be inserted in an exterior body, 0, of such size that it and the nipple will form a complete stopper to the tube A.

In practice I have found white-wood and bass-wood serve a good purpose for the part 0, being yielding enough to be driven as a stopper, and yet rigid enough to stand such a shock or blow on the nipple as will break it. I prefer woodbecause of its cheapness, and because the extinguisher can be packed as soon as stopped, whereas some time is required for cement to dry; but if wood be used for the surrounding part 0, it should be treated in hot paraffine to prevent the absorption of moisture, and after being so treated the periphery of the hole through the wood should be heavily coated with red lead and oil, the glass nipple inserted therein, and the parts laid aside for about two days to dry, after which the exterior of the part 0 is to be painted with red lead or like material and inserted in the tube A by any suitable stopper-machine.

It is proper to observe that where the stoppers are driven after the tubes are filled,which is generally so done, a small vent-hole, a, must be formed through the part O-otherwise the setting of the stopper will burst the tubc-the hole being after ward closed bya plug and paint.

Figs. 1 and 2 represent tapered nipples,

which are employed in that form that they may not be forced out by the pressure from the fluid, and in case of such pressure the metal of the tube A should be creased into the stopper, as shown at E, said crease forming a suitable means for attaching a wire, D, for hanging up the extinguisher. At Fig. 2 it will be seen that the under end of the part 0, J

surrounding the nipple is rimmed out, so as to form an inward and upward incline for the better escape of the fluid where a small nipple is used. Experiments show this to be an advantage; but I find that the end of the invention is attained by ahollow nipplesurrounded by the body 0, and the nipple projecting far enough beyond the tube A to be readily broken for the liberation of the fluid.

I claim as my invention-- l. In hand-tubes for holding and throwing a fire-extinguishing fluid onto a fire, a stopper for such tube, composed of a frangible nipple, B, which 'is hollow and headed at its outer end and'inserted in a surrounding body, 0, so as to project beyond the tube A, and the nipple and the surrounding part 0 forming a stopper, combined with the said tube, and the nipple being constructed to be broken off, leaving the part 0 in the tube, as specified, and for the purpose set forth.

2. The conical nipple B, which is hollow, and headed at its outer end, set in a surround ingpart, C, so that where the part 0 is driven into the tube A the nipple will project beyond the tube, the nipple and the surrounding part forming a complete stopper where combined with the tube A, the metal of the tube being creased into the part 0 at E, as and for the purpose set forth.

3. As anew article of manufacture, a hand fire-extinguisher with which a liquid charged with gases is employed, comprising a tube closed at one end and provided with a hollow frangible stopper at the other, the stopper being made separate from the tube, and when applied extending above or beyond its end.
